Abstract

Laser welding is a commonly used process to assemble medical devices. The heat produced during the laser welding process may have an adverse effect on the mechanical integrity of the case assembly and the functionality of heat sensitive electronic components. In order to maintain the mechanical integrity of the case assembly and to protect the subcomponents, it is important to control the temperature in the assembling process, the investigation of the temperature distribution in the assembly during laser welding is thus necessary. In this paper, we report an experimental method and a numerical simulation for the investigation of the temperature field in the process of laser welding the eyelet to the case subassembly of the Functional Electrical Battery Powered Microstimulator (FEBPM). A pulsed 1064nm Nd:YAG laser is used as an example in this paper.
